Electrical Training Dual Tube Rheostat Manufacturer,Supplier and Exporter in India

Product Code : SCL-EE-12719

The Electrical Training Dual Tube Rheostat is a dual-tube variable-resistance physics laboratory apparatus used to control current in low-voltage circuits for Ohm’s law, resistance variation, current control, voltage-drop study, and practical electricity training. It is suitable for schools, colleges, physics labs, STEM classrooms, distributors, and institutional procurement teams.

Product Description

Electrical Training Dual Tube Rheostat from School Equipments India is intended for supervised physics and electrical laboratory experiments. A rheostat acts as an adjustable resistance in a circuit, allowing students to vary resistance and observe the effect on current. The dual-tube format is taken from the product name; exact tube material, winding material, resistance range, current rating, slider design, terminals, dimensions, and calibration status must be confirmed from the final supplied product.

This apparatus helps students connect electrical theory with measurable circuit behaviour. It supports practical lessons on Ohm’s law, variable resistance, series circuits, current limiting, voltage drop, and safe adjustment of laboratory circuits. It should not be described as a precision calibration instrument unless valid calibration documentation is supplied.

Key Features

• Dual-tube rheostat format: suitable for practical circuit training where a dual-tube construction is required.
• Variable-resistance function: used to adjust circuit resistance during supervised electricity practicals.
• Current-control support: helps students observe how current changes when resistance is increased or decreased.
• Ohm’s law teaching value: supports voltage, current, and resistance relationship demonstrations.
• Hands-on training apparatus: useful for wiring practice, meter reading, and controlled laboratory observation.
• Construction to confirm: tube material, winding, slider, base, terminals, and insulation details must be verified.
• Rating to confirm: resistance range, current limit, power rating, and tolerance should be checked before procurement.

How to Use the Electrical Training Dual Tube Rheostat

1. Check the product label, resistance range, current rating, terminals, and experiment instructions before use.
2. Keep the power supply switched off while making all circuit connections.
3. Connect the rheostat in the required circuit position using suitable laboratory leads.
4. Set the slider or control to the safe starting position recommended by the teacher.
5. Switch on only the approved low-voltage laboratory supply.
6. Move the slider gradually and observe ammeter and voltmeter readings.
7. Record values at different resistance settings without exceeding the confirmed rating.
8. Switch off the supply before disconnecting, repositioning, or storing the apparatus.

Safety note: Use only under teacher or laboratory-supervisor control. Do not overload the rheostat, connect it directly to mains voltage, touch terminals during live experiments, or continue use if heating, sparking, burning smell, or unstable readings occur.

Care & Maintenance

• Store in a dry, dust-free cabinet after practical sessions.
• Keep slider contacts, terminals, tube surfaces, and connection points clean and corrosion-free.
• Do not exceed the confirmed current, voltage, or power rating.
• Quarantine the apparatus if the slider is loose, winding is damaged, terminals overheat, or readings become unstable.
